SIFTER TOP FOR CONTAINERS.

Application filed April 17, 1923. Serial N0. 632,625.

To all whom it may concern:

Be it known that I, HENRY PEIRCE BRAWNER, a citizen of the United States,

residing at Baltimore city, State of Maryland, have invented certain new and useful Improvements in Sifter Tops for Containers, of which the following is a specification.

This invention relates to a sifter top for tin boxes and other containers, one of the objects being to provide a structure of this character the parts of which can be assembled readily, there being a valve disk having novel means for holding it in position and for limiting its movement.

A further object is to provide a sifter top formed of few parts, efficient in use, and that will not readily get out of order.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts which will be hereinafter more fully described and pointed out in the claim, it being understood that various changes may be made in the construction and arrangement of the parts without departing from the spirit of the invention as claimed.

In the accompanying-drawings the preferred form of the invention has been shown.

In said drawings Figure 1 is a side elevation of the sifter to Figure 2 is an elevation taken at right angles to Figure 1.

Figure 8 is a plan view.

Figure 4: is an enlarged view similar to Figure 2 showing the retaining cap and the tongue of the valve disk in section.

Figure 5 is an enlarged section on line 55, Figure 3.

Figure 6 is an enlarged section on line 6 6, Figure 3.

Figure 7 is a plan view of the valve diskf Figure 8 is a plan view of the neck of the container with the disk and cap removed.

Referring to the figures by characters of reference 1 designates the neck of a container the end of which is closed, as at 2 and provided With an annular rib 3. A circular depression or channel 4: is provided in said end of the neck and is concentric therewith, there being a broad extension of the channel extended to the periphery of the neck, as shown at 5. An annular concentric groove 6 is formed in the bottom of the channel and that portion of the end of the neck surrounded by the channel and groove is provided with small openings 7.

Fitted snugly on the closed end of the neck is a valve disk 8 having a circular rib 9 pressed therefrom and adapted to fit in the groove 6. The marginal portion of the disk is adapted to rest on the bottom of the channel 4 and a tongue 10 that extends from the edge of the disk projects through the channel extension 5. This tongue is preferably downturned at its end, as shown at 11. Openings 12 are formed in the disk and. are so located that when the tongue 10 is against one end wall of the extension 5, they will register with the openings 7. When the tongue is moved away from that position, however, the openings 7 will be closed.

It will be noted from the drawings that when the disk 8 is in position it is substantially flush with the extreme end of the neck 1 of the container. It is held against lateral or radial displacement by the wall of the depression 4 and by the rib 9 in groove 6. For the purpose of holding the parts against separation there is provided a cap 13 the periphery of which is turned down and pressed into engagement with rib 3 as shown at 14. A portion of this periphery is cut away to provide clearance for the projecting tongue 10 and not limit the lateral movement thereof. This cut away portion is shown at 15 and there is provided on the upper wall thereof at the center, a projecting ear 16. When the tongue 10 is pressed to either limit of its movement it is snapped under and past this car and held thereby at either extreme position. The caphas openings 17 registering with the openings 7 in the end of the neck. Thus when the disk is moved to one position its openings 12 will register with the openings 7 and 17 and when moved to another position will close said openings. As shown in the drawings the cap 13 can be formed with a circular rib 18 on its inner face projecting into the groove formed in disk 8 by the v pression, there being an extension of the depression projecting to the margin of the neck, of an apertured valve disk rotatably seated in the depression, a tongue extending 5 therefrom and movable Within the extension of the depression, an apertured cap secured to the neck for retaining the disk in the depression, and an ear depending from the periphery of the cap for engagement by the tongue to hold the disk in either of two 1 extreme positions.

In testimony whereof I aflix my signature.

HENRY PEIR'CE BRAWNER.
